A couple of days ago I picked up a 1998 Forester, the main issue I am concerned with is a knocking sound in the engine. I think the knocking sound is a lifter. It is a small hammer tapping type sound. If the car is idling in neutral and I increase the rpm's a bit, the tapping normally stops. But if I am driving around town, just normal easy driving, the tapping stays. Under load 20-25 on a steep hill, level ground 20-35+, going downhill, etc, it seems to stay pretty much the same other than the tempo changing with rpm's. I keep thinking it sounds like a sticky lifter. A rod bearing should get louder under load? and a wrist pin quieter under load? If I remember correctly. I have looked up videos and they show the timing belt tensioner gone bad making a rattle, but this is not a rattle, it is a definite tapping that is in tune with the rpm's of the engine. The engine has 246,000 miles on it. I am considering pulling it and rebuilding it. Any opinions appreciated, Thanks. -
trying to eliminate my TOD (tick of death) or lifter tick and looking into maybe just making some adjustments along w/ using a heavier weight oil along with an oil treatment, but not sure i can make those changes if the rocker-arms are hydraulic. it would seem that based on the relative simplicity of the Loyale's engine, they'd be solid, but not sure. anyone got a firm answer for me? thanks much, Glen
